使用jquery对文本框进行集中处理

Question

I have two checkboxes like this:

<input id="isGenericPassword" name="isGenericPassword"
       onclick="IsGenericOrUnique(this.id);" type="checkbox" value="true" />
<input name="isGenericPassword" type="hidden" value="false" />
<input checked="checked" id="isUniquePassword" name="isUniquePassword"
       onclick="IsGenericOrUnique(this.id);" type="checkbox" value="true" />
<input name="isUniquePassword" type="hidden" value="false" />
<input id="UniquePassword" name="UniquePassword" style="display:none"
       type="text" value="" />

in document.ready, I have

 $('#isUniquePassword').is(':checked')
     ? $("#UniquePassword").show()
     : $("#UniquePassword").hide();

so that related textbox is visible if checkbox is checked.

I am hiding the textbox UniquePassword on click of isUniquePassword checkbox

$("#isUniquePassword").click(function () {
    $("#UniquePassword").toggle(this.checked);
    if ($("#isUniquePassword").is(':checked')) {
        // unique password gets focus only if related checkbox is checked
        $("#UniquePassword").focus();
    }
});

and show dialogue when user tries to go away without typing anything

 $("#UniquePassword").blur(function () {
     if ($("#isUniquePassword").is(':checked') &&
         $("#UniquePassword").val() == '')
     {
         $("#dialog-RecipientEmail-error").dialog("open");                        
     }
 });

and on Ok button click of that dialogue, setting focus again to that textbox so that value is entered

  $("#dialog-RecipientEmail-error").dialog({
      autoOpen: false,
      resizeable: false,
      width: 300,
      modal: true,
      buttons: {
          "OK": function () {
              $(this).dialog("close");
              $("#UniquePassword").focus();
          }
      }
  });

No I want that if isGenericPassword is checked or isUniquePassword is unchecked then I should get that error dialogue

Answer 1

$("#UniquePassword").focus(); will not focus the field rather it will trigger the actions which are bound with focus event. To focus a field, you need to get the handle of the HTML element

$("#UniquePassword").get(0).focus();

That should work.
